I see William gave you quite a bit, but I found the family in 1861 for you.
1861 WELLINGTON, CANADA WEST (ONTARIO) SMALL
John, age 29, farmer, born England
Jess, age 26, born Scotland
James H., age 9, born Lower Canada
Jess, age 7, born Upper Canada
Mary, age 5, born Upper Canada
Robert, age 3, born Upper Canada
David, age 1,born Upper Canada
Interesting bit here is that son James is shown born Lower Canada, rest of children born Upper Canada. Lower Canada was a term for Quebec and Lower Canada for Ontario. I did not find a baptism for James in Quebec records, nor a marriage for John and Jessie so that may have been an error in the census.
